Why is a roller coaster not in the first law of thermodynamics?

Actually it is. The first law of thermodynamics tells us that you have to put energy into the roller coaster (in this case in the form of work) to get it to the top of the first hill; getting it to the top increases its potential energy. Once it starts moving down, most of that potential energy is converted to kinetic energy as it moves around the track. Over the course of its circuit of the track, energy is continuously converted back and forth between potential and kinetic energy - with some energy also being converted to heat through friction with the rails and with the air. Energy is conserved - thus we see the first law obeyed.

How does Newton's Third Law relate to a rollercoaster?
Newton's second law (Force equals mass times acceleration, F = ma) deals with acceleration so it "takes effect" every time that the roller coaster speeds up, slows down or turns (horizontally or vertically).Basically Newton's second law just says that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to the mass of the object. Or, in other words, the harder you push the faster it speeds up and the bigger it is the slower it speeds up (or slows down - deceleration is an acceleration).This means that in your roller coaster example, the object is the roller coaster and the force can be: The motors that start the coaster and lift it up hills. The brakes that slow it down. Gravity which pulls it down the hills. The rails and wheels which cause the roller coaster to turn around bends, etc. At each of these points, Newton's second law is at play, determining how much acceleration will result from the force applied to the roller coaster's mass.
Different ways to state the first law of thermodynamics?
The first law of thermodynamics states that whenever energy is converted from one form to another, the total quantity of energy remains the same.
How many thermodynamics laws are there?
Basically four: the zeroeth law, the first law, the second law and the third law.
How does newtons third law relate to a roller coaster?
Whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first. Since a roller coaster is on a ramp, the ramp has to support the (apparently larger) weight of the roller coaster, especially when it turns it back up against gravity at the bottom of each incline. The rollers on each car also prevent the cars from leaving the track on turns, by exerting a controlling force using the sides and upper half of the track.
What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
Examples of the first law of motion?
kinda like a roller coaster going up or down
Which law of Thermodynamics states that energy cannot be created or destroyed?
That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.
What law of thermodynamics states that energy is neither created or destroyed?
The First Law of Thermodynamics.
What law says that energy cannot be created or destroyed only changed?
It is called the First Law of Thermodynamics, sometimes also called The Law of conservation of energy.
What law of thermodynamics states that different forms of energy can be converted into one another?
That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
When the law of conversation of energy is applied to heat it is known as the law of thermodynamics?
Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").
The first law of thermodynamics is related to the conservation of which quantity?
Yes. There are no known exceptions - otherwise it would not be considered a law
The fact that usable energy is always lost in an energy transfer is due to what 1 Newton's first law of motion 2 the second law of thermodynamics 3 Newton's second law of motion 4 the first l?
The second law of thermodynamics.
What is universal law of energy?
There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.
What is another name for the first law of Thermodynamics?
Law of inertia
